Wera Impaktor '851/1 IMP DC PH DIY' 25mm PH2 Impact Screwdriver Bits - Pack of 10

The Wera Impaktor 25mm PH2 bit is particularly suitable for use with conventional impact drivers and the rough diamond coating reduces the danger of any slipping out of the screw head due to the enhanced frictional resistance.

Maximum utilisation of the material properties, a very special geometry - designed particularly to meet the extreme demands - as well a specific manufacturing process mean that Wera Impaktor tools have an above-average service life.

Another advantage is the coating of the Impaktor bits with minute diamond particles. These diamond particles reduce the cam-out effects - particularly high in power tool applications - which can lead to a slipping out of the screw head. The diamond particles literally bite themselves into the screw recess. This means that less contact pressure is required, something that greatly delays fatigue setting in power tool screwdriving jobs.

For use with impact screwdrivers. Improve productivity when screwdriving with power tools. Maximum utilisation of the material properties, a very special geometry - designed particularly to meet the extreme demands - as well a specific manufacturing process mean that Wera Impaktor tools have an above-average service life.

Torsion zone specially designed to absorb such forces and thereby protect the bit tip. These diamond particles reduce the cam-out effects - particularly high in power tool applications - which can lead to a slipping out of the screw head.

The diamond particles literally bite themselves into the screw recess. This means that less contact pressure is required, something that greatly delays fatigue setting-in in power tool screwdriving jobs.
